NAME

Mail::Message::TransferEnc - message transfer encoder/decoder

INHERITANCE

 Mail::Message::TransferEnc
   is a Mail::Reporter

 Mail::Message::TransferEnc is extended by
   Mail::Message::TransferEnc::Base64
   Mail::Message::TransferEnc::Binary
   Mail::Message::TransferEnc::EightBit
   Mail::Message::TransferEnc::QuotedPrint
   Mail::Message::TransferEnc::SevenBit

SYNOPSIS

 my Mail::Message $msg = ...;
 my $decoded = $msg->decoded;
 my $encoded = $msg->encode(transfer => 'base64');

DESCRIPTION

This class is the base for various encoders and decoders, which are used during transport of the message. These packages, and all which are derived, are invoked by the message's Mail::Message::decoded() and Mail::Message::encode() methods:

 my $message = $folder->message(3);
 my $decoded_body = $message->decoded;
 my $encoded_body = $message->encode(transfer => 'base64');

The following coders/decoders are currently available:

*

Mail::Message::TransferEnc::Base64

"base64" for binary information.

*

Mail::Message::TransferEnc::SevenBit

"7bit" for plain old

ASCII

characters only.

*

Mail::Message::TransferEnc::EightBit

"8bit" for extended character set data, not encoded.

*

Mail::Message::TransferEnc::QuotedPrint

"quoted-printable" encdoded extended character set data.

Extends ``

in Mail::Reporter.

METHODS

Extends `` in Mail::Reporter.

Constructors

Mail::Message::TransferEnc->new(%options)

Inherited, see ``Constructors'' in Mail::Reporter

The Encoder

Mail::Message::TransferEnc->addTransferEncoder($type, $class)

Adds one new encoder to the list known by the Mail::Box suite. The $type is found in the message's header in the "Content-Transfer-Encoding" field.

$obj->create($type, %options)

Create a new coder/decoder based on the required type.

$obj->name()

The name of the encoder. Case is not significant.

Encoding

$obj->check($body, %options)

Check whether the body is correctly encoded. If so, the body reference is returned with the "checked" flag set. Otherwise, a new object is created and returned.

 -Option     --Default
  result_type  <type of source body>

result_type =>

CLASS

The type of the body to be produced, when the checker decides to return modified data.

$obj->decode($body, %options)

Use the encoder to decode the content of $body. A new body is returned.

 -Option     --Default
  result_type  <type of source body>

result_type =>

CLASS

The type of the body to be produced, when the decoder decides to return modified data.

$obj->encode($body, %options)

Use the encoder to encode the content of $body.

 -Option     --Default
  result_type  <type of source body>

result_type =>

CLASS

The type of the body to be produced, when the decoder decides to return modified data.

DIAGNOSTICS

Error: Decoder for transfer encoding $type does not work: $@

Compiling the required transfer encoding resulted in errors, which means that the decoder can not be used.

Warning: No decoder for transfer encoding $type.

A decoder for the specified type of transfer encoding is not implemented.

Error: Package $package does not implement $method.

Fatal error: the specific package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package.
